Flight along cosmic strings

So far the only scientifically proven the possibility of interstellar travel is the acceleration of the spacecraft up to relativistic speeds (punctures and convolution space still remain purely speculative projects). The ship may abandon astronauts in suspended animation for a dozen or even a hundred light years and return them to Earth. But because of the relativistic slowing of Board time on earth will pass away not even the century and Millennium — and it is somehow not pleasing. In addition to other galaxies to get to, there’s no cryostasis will not help. But it is possible that the output is still there.

For 15 years Professor of theoretical physics at Imperial College London, Joao Magueijo develops the hypothesis of variable speed of light (Varying Speed of Light, VSL). However, he minded very little, since most scientists believe this idea is pure nonsense. But we are talking about science impossible, so will try to temper my skepticism.

VSL-models calculated in several ways. They all say that measured on Earth the speed of light in a vacuum is not an absolute constant, and only the lower limit of the speed of propagation of electromagnetic waves. In certain (frankly, vesimaailma) conditions may be many times 299 792 km/s. Continue reading

Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

Something beyond Neptune

Astronomers have discovered the 9th planet of the Solar system?

Giant in the Kuiper belt

Perhaps, the ideas of humans about the Solar system far from reality. Scientists from the University of California, Michael brown and Konstantin Batygin has published a paper in which it is proved that in the Solar system there is at least one full planet .

For the first time sensational work of scientists was published in The Astronomical Journal, later it was reported by reputable scientific journals Science and Nature.

As stated in the work, a new planet, still do not have own names, was found by mathematical analysis of perturbations that experience the body the so-called “Kuiper belt” — space on the outskirts of the Solar system.

According to the calculations of brown and batygina, the ninth planet orbit is at a distance of 20 orbits from Neptune. Revolution around the Sun, this object travels in 10 – 20 thousand years. Planet, according to the findings of researchers exceeds the Land mass 10 times. Continue reading
